Project 3061 (Run 2, Clone 5, Gen 7)

This WU will run to 24% and then crash out:

[08:35:32] Completed 1200000 out of 5000000 steps (24 percent)
[08:35:32]
[08:35:32] Writing local files
[08:35:32] Completed 1200000 out of 5000000 steps (24 percent)
[08:35:32] Extra SSE boost OK.
[08:50:32] Timered checkpoint triggered.
[08:53:53] Warning: long 1-4 interactions
[08:53:55]
[08:53:55] Folding@home Core Shutdown: INTERRUPTED
[08:53:59] CoreStatus = 0 (0)
[08:53:59] Client-core communications error: ERROR 0x0
[08:53:59] Deleting current work unit & continuing...


It was happening on my 8 core (2 X quad core) MacPro.
Mac OS X 10.4.11

I restarted the WU and it crashed again. I moved the WU to a Core Duo Mac Mini. Same result.

If someone wants more info, there's a zip file of all the working files at:

The message long 1-4 interactions is generally associated with protein atoms that are positioned incorrectly and cannot be simulated. Some WUs will inevitably reach conditions like this and if it's because of your hardware, it's probably not going to repeat exactly. If it's because of the configuration itself, the WUs with this error should be rare and should be ignored. We all get a few like that.

I didn't say that ....

It's a good idea to report anything that says Deleting current work unit & continuing... but don't be surprised if you process the same WU 3 or 4 times before getting something new.

Did this work unit stop in the same place each time? or differnt % completed?

It's most likely a bad work unit, by your description of the symptoms. And no one else has completed this WU either, so that's my diagnosis. Move on to the next WU. Thanks for the report.
